Error "OVF descriptor is not available" when deploying Aria Operations Appliance

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• When attempting to deploy the Aria Operations Appliance at the cluster level in vCenter, the deployment fails with an error message similar to:
  
  Status: Failed to deploy OVF package
Cause: A general system error occurred: Transfer failed: The OVF descriptor is not available
  
  

Environment

VMware Aria Operations 8.x
vCenter 7.x and later

Cause

The error occurs due to an issue with the Content Library service in vCenter. This service is responsible for managing the deployment of OVF packages, and any problems with it can lead to errors like the one described

Resolution

To resolve the issue, follow these steps:

1. Take a snapshot backup of the vCenter Server Appliance before proceeding.
2. Execute the following commands in sequence to restart the Content Library service:
   • • service-control --stop vmware-content-library
     • service-control --start vmware-content-library
3. After restarting the service, retry importing the Aria Operations Appliance OVA, following the guidelines outlined in the Create a Aria Operations Node by Deploying an OVF documentation to complete the installation.

Additional Steps if Issue Persists :

If restarting the Content Library service does not resolve the issue, please:

• Open a Service Request with the vCenter server team, referencing this KB article, so they can further investigate and resolve the root cause of the issue
